LOCK-COCK.

spcieation of Letters Patent.

Application filed April 11, 1911.

Serial No. 620,481.

To all whom it may concern:

Y Be it known that I, CARL S'rrrr, a subject of the German Emperor, and a resident of Honolulu, in the county of Honolulu and Territory of Hawaii, have invented a new and Improved Lock-Cock, of which the following is a full, clear, and exact description.

My invention relates in general to a means for locking the stop cocks of faucets, and more particularly is adapted for use in locking a gasolene pump cock to prevent surreptitiously stealing of the gasolene from garages. i*

The main object of this invention is to provide an extremely simple article of this character, which can readily be applied to the ordinary type of structure, and which will, at the same time, constitute an effective lock for preventing the turning of the valve or cock.

A further object of my invention is to provide a device whereby the key may be fastened in a non-operative position to the body of the structure, and, at the same time, prevent the actuation of the valve by any other tool.

I attain these objects by locking the key in position on a part of the faucet, to engage a recess in the valve stem, thus preventing rotati'n of the-same.

With the above and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures, and in which- Figure l is a perspective view showing a preferred embodiment of my invention; Fig. 2 is a longitudinal sectional view taken through my device; Fig. 3 is a plan view looking down upon the key positioned on part of the structure; and Fig. l is a transverse,sectional view taken on the line 4 4 of Fig. 2 and looking in the direction of the arrow.

In the disclosure I have shown a faucet having a valve casing 1 having attached to its mouth a common form of gasolene strainer 2 and having its opposite end screwthreaded at 3, to engage in an aperture in a gasolene tank or to engage a nipple et having an enlarged sleeve 5 upon which are external threads 6 to engage in a larger sized opening in the gasolene tank. Adjacent the threaded end 3 of the casing 1, is a rectangleshaped boss 7, the upper forward end of which is downwardly and inwardly beveled to form an overhanging shoulder 8, in which is adapted to be slid the beveled end 9 of Patented Jan. 16, 1912.

a key 10. This key rests on the upper part of the casing and extends forward to the stem 11 of the valve 12, which valve controls the flow of gasolene through the faucet. The valve shell 13 is flared outward, as shown at 14, above the upper edge of the casing 1, but is interrupted on its rear portion to form a recess 15, into which recessed portion extends the projection 16 of the key 10. This projection has a blunt nose 17 engaging one side 18 of the rectangle-shaped stem 11. One end of the key 10 is reinforced, as shown at 19, which reinforced portion has a rectangle-shaped aperture 20 extending therethrough, and is adapted to fit on the similarly shaped stem 11 of the valve 12. Another portion of the key, preferably adjacent the opposite end from the reinforced portion 19, is enlarged, as shown at 21, which enlarged portion is perforated transversely, as shown at 22, which perforation is adapted to receive a locking element of any preferred form of padlock 23.

In order to draw gasolene through this faucet, it is necessary to unlock the padlock 23, raise the key 10 out of its position against the stem 11 of the valve 12, and place the aperture 20 over the stem 11, as shown in dot-ted lines in Fig. 2, whereby the faucet may be opened or closed. Then, in order to lock this in either the open or closed condition, the key is reinserted on its seat, as shown in Fig. 1, and the lock 23 is placed in position, locking the valve in the desired position.

Many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope'thereof. It is intended that all matters contained herein, in the above description, or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claim is merely intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween, and that materials, sizes and relativities of parts are non-essential, except as called for in the claim.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A faucet having a valve casing with a valve stem extending therethrough and projecting above said casing, the projecting part of said stem having a longitudinally-extending recess therein, a boss integral with said casing, the forward end of which is beveled to form an over-hanging shoulder spaced from the stem, a separable locking key adapted to be positioned on said stem, to actuate the same, said key having a beveled end adapted to fit beneath the overhanging shoulder, the other end of which key has a projection adapted to fit in said recess, to preventthe rotation of the stem, and means locking said key in position.

In testimony ywhereof I have signed my name to this specilicat-ion in the presence of two subscribing witnesses.

CARL STIFT.
